Hypnogram and Hypnodensity Analysis of REM Sleep Behaviour Disorder Using Both EEG and HRV-Based Sleep Staging Models.

Rapid-eye-movement (REM) sleep behaviour disorder (RBD) is a primary sleep disorder strongly associated with Parkinson's disease. Assessing sleep structure in RBD is important for understanding the underlying pathophysiology and developing diagnostic methods. However, the performance of automated sleep stage classification (ASSC) models is considered suboptimal in RBD, for both models utilising neurological signals ("ExG": EEG, EOG, and chin EMG) and heart rate variability combined with body movements (HRVm).

New minimally invasive technique for repositioning of a subluxated retropupillary iris-claw IOL using needle-assisted fixation.

Purpose: This paper presents a modification of the needle-assisted retropupillary fixation technique for iris-claw intraocular lenses (IOLs). We introduce a novel, minimally invasive reenclavation technique for managing subluxated retropupillary iris-claw IOLs.

Methods: The technique was successfully performed on four patients diagnosed with subluxated retropupillary iris-claw IOLs.

Sex differences in atrial remodeling and atrial fibrillation recurrence after catheter ablation.

Background: Women undergoing catheter ablation (CA) for atrial fibrillation (AF) reportedly have higher recurrence rates despite being generally less prone to developing AF. It remains unclear whether these sex differences are primarily driven by intrinsic disparities in atrial remodeling or by a greater burden of comorbidities.

Objectives: The purpose of this study was to evaluate sex-specific differences in AF recurrence after CA, identify modifiers of the prognostic effect of sex, and evaluate atrial remodeling using new echocardiographic parameters.

Compressive Pantyhose Mitigates Muscle Fatigue in Ballet-Specific Test: A Pilot Study.

Compression garments, utilized in sports and exercise for performance enhancement and recovery, lack sufficient well-controlled studies to overcome any potential placebo effect. Therefore, we tested whether wearing compressive pantyhose (CP) during the Ballet-specific aerobic fitness test (BAFT) would influence performance, recovery, physiological, and perceptual indicators. Additionally, this pilot study tested the feasibility of the research procedures and informed adjustments for the main study.

Breathtaking dreams: reduced REM phenotype in REM-related sleep apnea.

Purpose: The expression of the respiratory events in OSA is influenced by different mechanisms. In particular, REM sleep can highly increase the occurrence of events in a subset of OSA patients, a condition dubbed REM-OSA (often defined as an AHI 2 times higher in REM than NREM sleep). However, a proper characterization of REM-OSA and its pathological sequelae is still inadequate, partly because of limitations in the current definitions.
